Both of these coins are centralized and although the financial bodies are partnering with xrp, it doesn't mean Libra will get that support. They all put forward what they want and if facebook can do that, they won't get partnerships. I know facebook's CEO is one guy who like to do things by himself and no partnerships. This may affect him.

The fact and bottom line is that Libra may be widely accepted but it may not be able to compete with bitcoin and the old currencies and even if things are done underground, to make Libra the best coin,  it shall be noted. We all know of how people criticize xrp for the kind of management that goes on with xrp issuance.
